心房顫動信號處理及社區(qū)心臟病人監(jiān)護(hù)系統(tǒng)研制
[Abstract]:At present , most of the extraction algorithms of atrial fibrillation ( AF ) signal are directed to multi - lead electrocardiogram ( ECG ) , while multi - lead monitoring is not very mobile in ECG monitoring . Because of its flexibility and convenience , the single - lead monitoring system will become the development trend of the future " mobile " atrial fibrillation monitoring system . This paper mainly studies the extraction of single - lead AF signal , the classification of AF type and the development of remote ECG monitoring and diagnosis system .
This paper presents a new method for extracting atrial fibrillation signal from single lead ECG . The results show that the new method can extract the atrial fibrillation signal from single lead ECG well , and the calculation time is short , which has the prospect of applying to real - time wireless AF monitoring system .
In order to deepen the understanding of AF self - termination mechanism and improve the treatment of persistent AF , this paper studies the classification of paroxysmal and persistent AF by analyzing the characteristics of atrial fibrillation signal by means of principal component analysis . The results show that the total accuracy rate is 92 % and the average accuracy is 77.12 % . The method can be used to classify the two kinds of atrial fibrillation well , and has certain guiding significance for the pre - determination of spontaneous termination of atrial fibrillation .
Finally , the remote ECG monitoring and diagnosis system is studied and developed in this paper . The main contents include the detection of ECG Q , R , S , P , T characteristic wave , data waveform display , real - time communication of ECG data of client and server , database management and patient ' s case management system . This work has certain application value in community medical system .
